Running Gear
Shop the parts that keep your trailer rolling, stopping, and tracking the way it should. From hub-and-drum kits and brake backing plates to U-bolt kits, shackles, and spring-mount hardware, this collection is built for serious repair work and clean fit-up.
Backing plates, complete brake assemblies, and upgrade kits for common trailer axle setups.
Hub, drum, and bearing combinations that help simplify replacement and conversion work.
Wide and round U-bolt kits, tie plates, and hardware sized for real axle beam service.
Shackle bolts, equalizer hardware, and the small parts that restore a tired running gear system.
Overview
Running gear is where trailer reliability gets decided. This collection brings together the core parts most customers need when a trailer is due for brake work, hub replacement, spring hardware service, or a full axle-side refresh. Whether you are replacing one failed component or planning a more complete rebuild, this is the place to start with the parts that do the real work underneath the trailer.
R&P Service Insight
Most running gear problems do not stay isolated for long. When one component is worn, overheated, bent, or seized, the surrounding parts usually deserve inspection too.
- Brake Jobs: Check brake size, mounting pattern, and left/right orientation before ordering.
- Hub Service: Confirm bearing numbers, grease seal dimensions, and wheel bolt pattern rather than guessing by axle rating alone.
- Suspension Hardware: Verify axle tube size, spring width, U-bolt style, and tie-plate fit before install day.
R&P Knowledge Hub
- Brake assemblies: Always verify diameter, width, flange bolt pattern, and side-specific fitment.
- Hub and drum kits: Match bearing set, grease seal, wheel bolt pattern, and brake diameter to your axle setup.
- U-bolt kits: Tube diameter and spring-seat width matter. A nearly right kit is still the wrong kit.
- Backing plates and rebuild parts: Confirm whether you need complete assemblies or individual service components before ordering.
